Final answer:
The correct date to enter in Block 14 for Jean Mandel's CMS-1500 is 05 05 YYYY since that is the date calculated by going back five days from the present date, which accounts for the onset of symptoms.
Step-by-step explanation:
The correct entry for Block 14 on the CMS-1500 claim form for Jean Mandel would be 05 05 YYYY. This is because the provider documented that the patient's pain began five days prior to the current date, which is noted as May 10, YYYY. As such, by counting back five days, we land on the date of May 5, YYYY, which is the onset of the patient's signs or symptoms.
In Block 14 of the CMS-1500 claim, you would enter the date the patient first experienced signs or symptoms of an illness or injury. In this case, Jean Mandel's pain began five days ago. Today is May 10, YYYY, so the date entered in Block 14 would be 05 05 YYYY.
